Three-Piece Ball Valve (Manual/Pneumatic/Electric)

Three-Piece Ball Valve offers diversified connections: Internal threads, industrial thick-wall pipe welding, sanitary thin-wall pipeline butt welding (compatible with automatic welding machines for extended automated welding), sanitary pipeline quick-connect, sanitary pipeline hygienic flanges, national standard pipeline GB flanges.

Three-Piece Ball Valve body adopts precision vacuum wax mold casting technology with optimized structure and aesthetic design. Elastic sealing structure ensures reliable sealing and smooth operation. Reverse-sealed bottom-loading stem design prevents stem ejection during abnormal cavity overpressure.

Three-Piece Ball Valve bodies feature ISO high platforms and locking mechanisms. Compatible with pneumatic/electric actuators, valve position feedback, mechanical/smart positioners to meet industrial automation requirements.
